Colin Kass is a partner in the Litigation Department and Co-Chair of Proskauer’s Antitrust Group. As a seasoned trial lawyer, Colin has handled many of the nation’s most complex and innovative antitrust cases over the past 20 years.

His practice involves a wide range of industries, including financial services, healthcare, sports, media, pharmaceuticals, and automotive markets, and spans the full-range of antitrust and unfair competition-related litigation, including class actions, competitor suits, dealer/distributor termination suits, price discrimination cases, criminal price-fixing probes, and merger injunctions.

Colin also has extensive experience interfacing with the Federal Trade Commission and Department of Justice, obtaining clearance for competitively-sensitive transactions and handling anticompetitive practices investigations.

As a trusted advisor, Colin also counsels clients on their sales, distribution, and marketing practices, strategic ventures, and general antitrust compliance.

When an enforcement action for a violation of the Hart-Scott-Rodino Act is announced, chances are the matter has already come to a close – by the time the action becomes public, the agency and the parties usually have agreed upon financial penalties and other sanctions to be levied. But that is not the case for ValueAct Capital and its affiliated investment funds. After the Department of Justice filed a complaint against ValueAct on April 4, the company did not take the allegations lying down. Instead, it vowed to vigorously defend its position.
